Description

Metal building fireproof roof system (1)

The present invention relates to a fireproof roof system for metal buildings (1), in particular to an M-shaped steel frame above the first steel plate, and then a first barrier layer is laid on the top of the first steel plate, so as to effectively delay the arrival of heat sources from bottom to top. The second steel plate delays the collapse of the metal building when a fire occurs. Or, a second barrier layer can be laid above the M-shaped steel frame to effectively prevent the heat insulation source from reaching the first steel plate from top to bottom, so as to maintain the room temperature in the building and reduce energy consumption. Moreover, the M-shaped steel frame reduces the contact heat conduction point with the second steel plate, effectively delaying the damage rate of the fire, so that the steel beams between the wheelbases can be evenly stressed, reducing the amount of steel used, and the construction is easier, and the supporting force can be directly Conduct upwards to comply with the fire-resistant roof system required by building laws and regulations such as fire-resistant, flame-resistant, and wind-resistant.

As shown in Figures 1 and 2, it is the first conventional fire protection building. The first steel plate a2 is installed above the C-shaped steel frame a1, and the U-shaped fixing seat a3 is installed above the C-shaped steel frame a1. A square steel frame a4 is set inside the fixed seat a3, and a support seat a5 is set above the square steel frame a4 to support the peak of the hidden second steel plate a6, and then lay it between the first steel plate a2 and the second steel plate a6 There is a fire protection layer a7 (the paving construction process, of course, is completed one by one from bottom to top). The first type of conventional person has complicated construction. It is necessary to bolt down from the first steel plate a2 to the C-shaped steel frame a1 by bolting element a8, and then use bolting element a9 to connect the square steel frame a4 with the U-shaped fixing seat. a3 bolting combination, and then bolting element a10 from the second steel plate a6 down to bolt the support seat a5 and the square steel frame a4, although the square steel frame a4 can evenly bear the weight from the second steel plate, However, the construction procedure is complicated and the cost is too high, and the area where the C-shaped steel frame a1, the U-shaped fixing seat a3 and the square steel frame a4 are in contact with each other is very large. The method solves the problem of excessive heat conduction area from high indoor temperature transfer from top to bottom or outdoor high temperature transfer from top to bottom. In this way, when a fire occurs in a building, the indoor high-temperature combustion flame will directly contact the first steel plate. When the aforementioned C-shaped steel frame a1, U-shaped fixing seat a3 and square steel frame a4 have a large contact area with each other, the high temperature in the free room will be transferred from bottom to top to the second steel plate, resulting in square steel frame a4. The rapid collapse with the second steel plate cannot effectively delay the speed at which the heat source is guided to the square steel frame a4 and the second steel plate, which limits the fire and flame resistance of metal buildings.

As shown in Figures 3 and 4, it is the second type of conventional fire protection building. A first steel plate b2 is installed above the C-shaped steel frame b1, and a Z-shaped steel frame b3 is installed above the first steel plate b2. A second steel plate b4 is laid on the top of the frame b3, and of course a fire protection layer b5 is placed between the first steel plate b2 and the second steel frame (the paving construction process is of course completed one by one from bottom to top). In the second type of prior art, the bolting element b6 passes down the first steel plate b2 from the lower plane of the Z-shaped steel frame b3 and then bolted down to the C-shaped steel frame b1, and then the bolting element b7 Bolt down from the second steel plate b4 to the upper plane of the Z-shaped steel frame b3, so that the force position of the Z-shaped steel plate is concentrated on the neutral surface of the Z-shaped steel frame b3, and cannot evenly bear the weight from the second steel plate. If you are not careful, the Z-shaped steel frame will deform and turn over, and the C-shaped steel frame b1 and the first steel plate b2, the first steel plate b2 and the Z-shaped steel frame b3, and the Z-shaped steel frame b3 and the second steel plate b4 will be between each other. The large contact area cannot solve the problem of excessive heat conduction area from high indoor temperature transfer from top to bottom or outdoor high temperature transfer from top to bottom. Therefore, when a fire occurs in a building, the indoor high-temperature combustion flame will directly contact the first A steel plate. At this time, because the aforementioned contact area is too large, the high temperature in the free room will increase from bottom to up to the second steel plate, causing the Z-shaped steel frame and the second steel plate to collapse quickly, which cannot effectively delay the heat source to the The speed of the Z-shaped steel frame and the second steel plate limits the fire and flame resistance of metal buildings.

As shown in Fig. 5, it is the third type of conventional fire protection building. The first steel plate c2 is installed above the C-shaped steel frame c1, and then the hat-shaped steel frame c3 is installed above the first steel plate c2, and the hat-shaped steel frame c3 Shop on top Set the second steel plate c4, and of course the fire-proof layer c5 between the first steel plate c2 and the second steel frame c4 (the laying construction process, of course, is completed one by one from bottom to top). The third conventional method uses bolting element c6 to pass through the first steel plate from the lower plane of the cap-shaped steel frame and then bolt down to the C-shaped steel frame. The steel plate is bolted down to the upper plane of the hat-shaped steel frame, so that the force position of the hat-shaped steel plate is concentrated on the middle elevation, and it is mutually drawn with the C-shaped steel frame, and cannot evenly bear the weight from the second steel plate. If you are not careful, the hat-shaped steel frame will be deformed, and the contact area between the C-shaped steel frame and the first steel plate, the first steel plate and the hat-shaped steel frame, and the hat-shaped steel frame and the second steel plate will be too large. It comes from the problem that the heat conduction area is too large when the indoor high temperature transfers upwards or the outdoor high temperature transfers from top to bottom. Therefore, when a fire occurs in a building, the indoor high-temperature combustion flame will directly touch the first steel plate. At this time, Because the aforementioned contact area is too large, the high temperature in the free chamber will be transferred from bottom to top to the second steel plate, resulting in the rapid collapse of the hat-shaped steel frame and the second steel plate, which cannot effectively delay the heat source from being guided to the hat-shaped steel frame and the second steel plate. Second, the speed of the steel plate limits the fire and flame resistance of metal buildings.

As shown in Fig. 6, it is the fourth conventional fire protection building. The first steel plate d2 is installed above the C-shaped steel frame d1, and the square steel frame d3 is installed above the first steel plate d2. The second steel plate d4 is laid on the upper side, and of course the fireproof layer d5 is placed between the first steel plate d2 and the second steel frame d4 (the laying construction process, of course, is completed one by one from bottom to top). The fourth type of conventional knowledge requires that the square steel frame must be punched in advance, and the processing procedures are too many and the cost is too high. And bolted element d6 from the lower plane of the square steel frame down through the first steel plate and bolted down to the C-shaped steel frame, then bolted element d7 from the second steel plate down to the square shape The upper plane of the steel frame, although the square steel frame can bear the weight from the second steel plate, the C-shaped steel frame and the first steel plate, the first steel plate and the square steel frame, the square steel frame and the second steel plate are mutually The large contact area between them cannot solve the problem of excessive heat conduction area from high indoor temperature transfer from top to bottom or outdoor high temperature transfer from top to bottom. Therefore, when a fire occurs in a building, the flame of indoor high-temperature combustion will directly When the first steel plate is contacted, at this time, because the aforementioned contact area is too large, the high temperature in the free room will be transferred from bottom to top to the second steel plate, causing the square steel frame and the second steel plate to collapse quickly, which cannot effectively delay the heat source The speed of guiding to the hat-shaped steel frame and the second steel plate limits the fire and flame resistance of the metal building.

As shown in Figure 7, it is the fifth type of conventional fire protection building. The first steel plate e2 is installed above the C-shaped steel frame e1, and the channel steel frame e3 is installed above the first steel plate e2. Lay the second steel plate e4, and then the fire protection layer e5 between the first steel plate e2 and the second steel frame e4 (the laying construction process, of course, is completed one by one from bottom to top). In the fifth type of prior art, the bolting element e6 passes through the first steel plate from the upper plane of the channel steel frame and then bolts down to the C-shaped steel frame, so that the cap of the bolting element e6 will be long-term Touching the peak or groove of the second steel plate, when the constructor is laying the second steel plate, the stepping process will easily cause the cap of the bolting element e6 to rub against the peak or groove of the second steel plate, causing secondary damage , The roof leaks.

As shown in Figure 8, it is the sixth conventional fire protection building. The first steel plate f2 is installed above the C-shaped steel frame f1, and then the C-shaped steel frame f3 is installed above the first steel plate f2, and the C-shaped steel frame f3 The second steel plate f4 is laid on the top, and of course the fire-proof layer f5 is placed between the first steel plate f2 and the second steel frame f4 (the laying construction process, of course, is laid one by one from bottom to top). The sixth conventional method uses the bolting element f6 from the lower plane of the C-shaped steel frame f3 to pass through the first steel plate and then bolt down to the C-shaped steel frame f1, and then use the bolting element f7 from the first steel plate. The two steel plates are bolted down to the upper plane of the C-shaped steel frame f3, so that the C-shaped steel frame cannot evenly bear the weight from the second steel plate. And because of the large contact area between the C-shaped steel frame f1 and the first steel plate, the first steel plate and the C-shaped steel frame f3, and the C-shaped steel frame f3 and the second steel plate, it is impossible to solve the problem from the high indoor temperature. Or the heat conduction area of the outdoor high temperature transfer from top to bottom is too large. Therefore, when a fire occurs in a building, the indoor high-temperature burning flame will directly contact the first steel plate. At this time, as mentioned above, the contact area will be too large. The increase comes from the transmission of the high indoor temperature from bottom to top to the second steel plate, causing the rapid collapse of the C-shaped steel frame f3 and the second steel plate. Collapse, unable to effectively delay the speed of the heat source guided to the C-shaped steel frame f3 and the second steel plate, resulting in limited fire and flame resistance of metal buildings.

As shown in Figures 9 and 10, it is the seventh conventional fire protection building. The first steel plate g2 is set above the C-shaped steel frame g1, and then the above-mentioned C-shaped steel frame g1 is in contact with the Z-shaped steel frame g3, and then the Z The second steel plate g4 is laid on top of the profiled steel frame g3 (the laying construction process, of course, is completed one by one from bottom to top). The seventh type of prior art uses the bolting element g6 from the lower plane of the Z-shaped steel frame g3 to pass through the first steel plate and then bolt down to the C-shaped steel frame, and then bolt the element g7 from the second The steel plate is bolted down to the upper plane of the Z-shaped steel frame, so that the Z-shaped steel frame cannot evenly bear the weight of the second steel plate and is easy to deform and turn over. Moreover, due to the large contact area between the C-shaped steel frame and the first steel plate, the C-shaped steel frame and the Z-shaped steel frame, and the Z-shaped steel frame and the second steel plate, it is impossible to solve the problem of the transmission from the high indoor temperature. The heat conduction area of the outdoor high temperature transfer from top to bottom is too large. Therefore, when a fire breaks out in a building, the indoor high-temperature burning flame will directly touch the first steel plate. At this time, as mentioned above, the contact area will increase The high temperature in the room is transferred from bottom to top to the second steel plate, causing the Z-shaped steel frame and the second steel plate to collapse quickly, which cannot effectively delay the heat source guiding to the Z-shaped steel frame g3 and the second steel plate, resulting in metal construction. The fire and flame resistance of objects is limited.

For this reason, the inventor of this case, based on the experience in the processing, manufacturing and construction of metal building materials, specially studied the problems of the previously disclosed technology.

And when a fire broke out, the first steel plate touched the fire site High temperature, with the first barrier layer that can withstand high temperatures up to 700 to 1000 degrees Celsius, delays the transmission to the M-shaped steel frame, delaying the time for the M-shaped steel frame to be rapidly destroyed and deformed, which is enough to pull and support the building structure without rapid collapse. Or, use the second barrier layer above the M-shaped steel frame to delay the temperature of the M-shaped steel frame to the second steel plate, and then use the second steel plate to pull and support the structure of the building, so that the building will not collapse quickly.

The second purpose of the present invention is to lock the bolting element down from the groove surface of the M-shaped steel frame into the first barrier layer to the first steel plate, so that the head of the bolting element can be buried in the M-shaped steel frame. The groove surface of the steel frame facilitates the laying operation of the second steel plate and avoids friction damage to the head of the bolted element on the inner protective layer of the second steel plate. Moreover, the present invention can be applied to the renovation of old houses, and the M-shaped steel frame can be directly installed on the roof, and then the second steel plate can be laid to achieve the purpose of rapid renovation.

Then set an M-shaped steel frame above the first barrier layer, set a second barrier layer above the M-shaped steel frame, and set a second steel plate above the second barrier layer, and bolt the first steel frame , The first steel plate, the first barrier layer, the M-shaped steel frame, the second barrier layer and the second steel plate are bolted. First block The compartments, M-shaped steel frame and the second set of compartments slow down the speed of heat conduction from top to bottom or bottom to top in order to comply with construction laws such as fire prevention, flame resistance, and wind pressure resistance.

The metal building fireproof roof system of the present invention can bear the weight of the second steel plate evenly by the M-shaped steel frame, and reduce the contact area between the M-shaped steel frame and the second steel plate or not contact at all, so that the second bolting element can be It is bolted in the groove surface of the M-shaped steel frame, and the cap of the second bolting element is hidden and sinking, eliminating the contact of the cap of the second bolting element with the second steel plate, and avoiding secondary damage The reason, and because the M-shaped steel frame bears the weight of the second steel plate on average, the neutral wheelbase has an even force, which reduces the amount of steel used, and the construction is faster and easier.

In order to enable your examiner to fully understand the metal building fireproof roof system (1) of the present invention, the following is explained with the accompanying drawings:

As shown in Fig. 11, the M-shaped steel frame 3 of the present invention includes: a first plane 31 to be attached to the upper side of the first steel plate 2, and a first elevation 32 is provided on both sides of the aforementioned first plane 31. The upper end of the first elevation 32 is provided with a second plane 33 inwardly for laying the second steel plate 4 and the second barrier layer 5a. When the bolting element is bolted from the second steel plate 4, it can be bolted into the first Two plane 33. The aforementioned second plane 33 is provided with a groove surface 30 to bury the head of the second bolting element 60, so that the M The profiled steel frame can bear the weight of the second steel plate 4 evenly, and can reduce the contact area between the M-shaped steel frame 3 and the second steel plate 4.

Figures 12 to 18 are application examples of the present invention, which include at least: the first steel plate 2, which can be a corrugated steel plate or a floor plate or other metal steel plates or punched steel plates 2a (as shown in Figure 16 for application example 2) For this reason, the aforementioned first steel plate 2 is arranged above the first steel frame 1 or steel beam, and the aforementioned first steel frame 1 or steel beam can be H-shaped or C-shaped (as shown in the application example 1 of Figures 14 and 15) or Tube or U-shaped or other shapes are all available. If the first steel plate 2 is set above the first steel frame 1, the first steel frame 1 is then bolted with a plurality of first bolting elements 10 and a plurality of L-shaped steel elements 11, and then the L-shaped steel element 11 and the steel beam (It belongs to conventional knowledge, so it is not shown in the figure) bolting or welding combination.

As shown in Figures 12-18, the first barrier layer 5 is laid on top of the first steel plate 2. The first barrier layer 5 is composed of fire-resistant, heat-insulating, flame-resistant, and sound-proof materials, and has high temperature resistance exceeding 700 degrees Celsius to 700 degrees Celsius. 1000 degrees to produce a better thermal barrier effect. M-shaped steel frames 3 are laid on the upper side of the first barrier layer 5 at appropriate intervals, and the number and position of the laying are most appropriate to match the position of the first steel frame 1. The second bolting element 60 can be bolted down from the groove surface 30 of the aforementioned M-shaped steel frame 3, passing through the first barrier layer 5 and the first steel plate 2, and then bolted into the aforementioned first steel frame 1 or steel beam, that is, the M-shaped steel frame 3, the first barrier layer 5, the first steel plate 2, the first steel frame 1 or the steel beam can be bolted in place, and the cap 600 of the aforementioned second bolting element 60 It can be concealed in the groove surface 30 of the aforementioned M-shaped steel frame 3 to prevent the cap 600 of the second bolting element 60 from contacting the second steel plate 4 and cause damage to the inner protective layer of the second steel plate 4. And because the first plane 31 of the aforementioned M-shaped steel frame 3 is blocked by the first barrier layer 5, the first steel plate 2 is not in contact with the M-shaped steel frame 3 (as shown in Figures 14, 17, and 18), thereby hindering Temperature from bottom to top. And by maintaining the smallest contact area between the second plane 33 of the aforementioned M-shaped steel frame 3 and the second steel plate 4 (as shown in the figure) 15) In order to delay the heat conduction speed from top to bottom, the present invention complies with construction laws and regulations such as fire resistance, flame resistance and wind pressure resistance.

As shown in Figures 11-18, it is located above the aforementioned M-shaped steel frame 3 and laid with a second steel plate 4, which can be a corrugated steel plate (as shown in Figures 13, 14 and 15) or a flat steel plate or a snap-fit hidden steel plate (as shown in Figure 17) Example 3) or stranded concealed steel plate (as shown in Application Example 4 in Figure 18) or steel plates of other shapes are all acceptable. Then the third bolting element 61 is bolted down from the second steel plate 4 to the second plane 33 of the M-shaped steel frame 3, so that the first steel frame 1 or steel beam, the first steel plate 2, The first barrier layer 5, the M-shaped steel frame 3 and the second steel plate 4 are bolted and combined. In this way, the aforementioned M-shaped steel frame 3 can be used to reduce the heat conduction point, and prevent the cap of the second bolting element from causing secondary damage to the second steel plate, and allow the M-shaped steel frame to bear the weight of the second steel plate evenly. The neutral wheelbase has an even force and can reduce the amount of steel used, making construction easier and faster. The first barrier layer 5 delays the heat source from bottom to top or the high temperature from top to bottom to ensure that the metal building complies with construction laws such as fire prevention, flame resistance, and wind pressure resistance.

As shown in Figures 19 and 20, the fifth application example of the present invention. The fifth application example is derived from the foregoing application examples, and at least includes: the first steel plate 2, which can be a corrugated steel plate or a floor plate or other metal steel plates or stamped The steel plate 2a of the hole (refer to the application example 2 in Figure 16) is this. The aforementioned first steel plate 2 is arranged above the first steel frame 1 or steel beam. The aforementioned first steel frame 1 can be H-shaped, C-shaped, tubular, U-shaped, or other shapes. If the first steel plate 2 is set above the first steel frame 1, the first steel frame 1 needs to be bolted with a plurality of first bolting elements 10 and a plurality of L-shaped steel elements 11, and then the L-shaped steel elements 11 and the steel The beams (belonging to conventional knowledge, so not shown in the figure) are bolted or welded together.

As shown in Figures 19 and 20, the first barrier layer 5 is laid on the first steel plate 2. The first barrier layer 5 is composed of fire-proof, heat-insulating, flame-resistant, and sound-proof materials, and has high temperature resistance exceeding 700°C to 1000°C. Degree to produce a better barrier effect. Above the aforementioned first barrier layer 5 is suitable When the M-shaped steel frame 3 is laid at a distance, the number and position of the laying are most appropriate to match the position of the first steel frame 1 described above. Then the second bolting element 60 is bolted down from the groove surface 30 of the M-shaped steel frame 3, passes through the first barrier layer 5 and the first steel plate 2, and then bolts into the aforementioned first steel frame 1 or steel The M-shaped steel frame 3, the first barrier layer 5, the first steel plate 2, the first steel frame 1 or the steel beam bolts can be fixed in place, and the cap 600 of the aforementioned second bolting element 60 can be sunk The groove surface 30 of the aforementioned M-shaped steel frame 3 prevents the cap 600 of the second bolting element 60 from contacting the second steel plate 4, causing secondary damage to the protective layer of the second steel plate 4. And because the first plane 31 of the aforementioned M-shaped steel frame 3 is blocked by the first barrier layer 5, the first steel plate 2 is not in contact with the M-shaped steel frame 3 (as shown in FIG. 20) to hinder the temperature from bottom to top . And by keeping the minimum contact area between the second plane 33 of the aforementioned M-shaped steel frame 3 and the second steel plate 4 (as shown in Figure 20), the heat conduction speed from top to bottom is delayed, so that the present invention meets the requirements of fire, flame, and wind resistance. Overwhelming construction laws.

As shown in Figs. 19 and 20, the second barrier layer 5a is placed above the M-shaped steel frame 3, and most of the second barrier layer 5a is in contact with the first barrier layer 5. The aforementioned second barrier layer 5a can be made of the same material or different material from the aforementioned first barrier layer 5, and the aforementioned second barrier layer is still composed of fire-retardant, heat-insulating, flame-resistant, and sound-proof materials, and can withstand high temperatures exceeding 700°C to 700°C. 1000 degrees to produce a better barrier effect.

As shown in Figures 19 and 20, above the second barrier layer 5a, it is located at the position of the second plane 33 of the M-shaped steel frame and is then laid with a second steel plate 4, which can be a corrugated steel plate (see Figures 13, 14 and 15) Or flat steel plate or buckle type hidden steel plate (refer to application example 3 in Figure 17) or stranded type hidden steel plate (refer to application example 4 in Figure 18) or other shapes of steel plates. It is all necessary to combine the aforementioned M-shaped steel frame 3 with The second steel plate 4 is isolated from contact. Then the third bolting element 61 is bolted down from the second steel plate 4 to the second plane 33 of the M-shaped steel frame 3, and the aforementioned first steel frame 1 or steel beam, first steel plate 2, first The barrier layer 5, the M-shaped steel frame 3, the second barrier layer 5a and the second steel plate 4 are bolted and combined. In this way, by the aforementioned The M-shaped steel frame 3 reduces the heat conduction point, and allows the aforementioned M-shaped steel frame to bear the weight of the second steel plate evenly, so that the neutral wheelbase is evenly stressed, and the amount of steel used can be reduced, making the construction easier and faster. Moreover, the first barrier layer 5 and the second barrier layer 5a completely block the heat source from bottom to top and the high temperature from top to bottom, so that the metal building complies with building laws such as fire resistance, flame resistance, and wind pressure resistance.

In summary, the metal building fireproof roof system (1) of the present invention reduces the contact area with the second steel plate by using the M-shaped steel frame, which can effectively slow down the high temperature generated by the two steel plates exposed to sunlight from top to bottom. The speed can ensure that the temperature change in the metal building will not be too large, reduce the continuous operation of the air-conditioning system, and save energy. Or the second barrier layer isolates the second steel plate from the M-shaped steel frame without contact, so that the high temperature generated by the second steel plate in the sun cannot be transmitted to the M-shaped steel frame, so as to ensure that the temperature changes in the metal building will not be too large , Reduce the continuous operation of the air-conditioning system and save energy. Or when a fire occurs, the first barrier layer is used to isolate the first steel plate from the high temperature from the fire field to slow down the transmission time to the M-shaped steel frame and the second steel plate, or the second barrier layer is used to isolate the M-shaped steel frame and the second steel plate. The second steel plate delays the transmission of the high temperature inside the metal building to the M-shaped steel frame and the second steel plate, and delays the time of the collapse of the falling building, which is enough to allow personnel to evacuate safely, ensure personnel safety, and improve the wind resistance of metal buildings , The fire and flame resistance coefficients are in line with the building regulations, which are the composition of the novelty and progress of this case.
